Replaced OVP. Bought it from the dealer. Hungary made. Two fuses/my old one was one fuse. Went ahead and used it anyway.

Results: 1. Never had a cold start problem but did have some stumbling after heading out in the morning...ony for a block or two. That has improved.
2. Warm restart is still needed sometimes. No improvement here
3. Overall performance of the car has improved. Car runs smoother and has more power. Shifts better somehow.
4. Rough idle. By rough idle I mean an idle that moves up and down like it is searching maybe 50-75 RPMs, sometimes a little more. No improvement here at all
5. Cold Idle did change from 750 to 900.
6. Warm Idle stays around 500-520 with searching sometimes around 500 575

Replacing the OVP felt like it fixed part of the problem. I suspect mixture adjustments done on this car will need to be readjusted now.

From other posts I am also wondering if the bolt under the rotor might be a culprit along with Idle Contol Valve lower hose, connector or unit itself.

Thanks to everyone. I will also check the o2 sensor and suggestions above.
